Concrete Polishing has got to be the most environmentally responsible choice you can make for your indoor flooring. Since it is already in most foundations you don't need to use extra resources to cover your floor, over and over. The polishing process is non-toxic, clean and does not harm the environment in any way. Adding non-toxic stain to the process is a water based endeavor so, you are not polluting. AND, your indoor environment is free from formaldehydes and other volatile organic compounds found in carpet glue, tile glue, and wood floor adhesives. Combine polished concrete with in-floor heating and you will have the most economical, environmentally clean floor available. It really is a choice you can feel good about.
